Description

The light-yellow shell has an elongate-conic shape. lts length measures 3.8 mm. The whorls of the protoconch are deeply obliquely immersed in the first of the succeeding turns. The six whorls of the teleoconch are cylindric in outline, moderately rounded in the middle and very much so at the very strongly shouldered summit. The sutures are well impressed. The periphery is short, the base of the body whorl is well rounded, the latter narrowly umbilicated. The entire surface of the spire and the base is marked by numerous vertical lines of growth and exceedingly fine, closely spaced, wavy spiral striations. The aperture is ovate. The posterior angle is obtuse. The outer lip is thin. The columella is slender, somewhat sinuous, slightly reflected, provided with a deep-seated fold a little anterior to its insertion;. The parietal wall is glazed with a thin callus.[3]

Distribution

This species occurs in the Pacific Ocean off San Diego, California.

gollark: Anyone with a screwdriver, the ability to look up tutorials and some sanity can repair a desktop computer (well, replace some parts). This isn't the case for phones - partly just because size constraints, but it's partly artificial.
gollark: People will mess things up but designing unrepairable devices DOES NOT HELP.
gollark: Or, well, Apple-derived thing which spread?
gollark: I think the practice of having the screen glass and touchscreen digitizer/display bit literally be fused together is an Apple thing.
gollark: Convoluted methods to disassemble devices create extra risk and make it harder for regular people to repair.
